[PMID: 37270058 DOI: 10.1016/j.recot.2023.05.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 05/17/2023] [Accepted: 05/30/2023] [Indexed: 06/05/2023] Open
Abstract
OBJECTIVE To analyze the efficacy and safety after the application of platelet-rich-plasma (PRP) as an adjuvant in arthroscopic rotator cuff repairs. MATERIAL AND METHODS A bibliographic search of the literature of prospective studies with level of evidence one or two was carried out from January 2004 to December 2021, including studies that compare the functional and re-tear results after arthroscopic cuff repair rotator with or without PRP. RESULTS A total of 281 articles were identified, of which 14 met the inclusion criteria. The overall re-rupture rate was 24%. In the PRP group, a decrease in the re-rupture rate and better functional results were demonstrated, although these differences were not significant. CONCLUSIONS Adjuvant treatment with PRP has shown promising results, although there is not yet enough evidence to provide a clear advantage for routine use in clinical practice.

Abstract
Background The therapeutic efficacy of orthobiologic therapies for rotator cuff repair is difficult to evaluate owing to reporting inconsistences. In response, the Minimum Information for Studies Evaluating Biologics in Orthopaedics (MIBO) guidelines were developed to ensure standard reporting on orthobiologic therapies. Purpose To systematically review clinical studies evaluating platelet-rich plasma (PRP) for full-thickness rotator cuff repair and adherence to MIBO guidelines. Study Design Scoping review; Level of evidence, 4. Methods A search was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using PubMed, EMBASE, and the Cochrane Library databases. Inclusion criteria were clinical studies reporting on rotator cuff tears (≥1 cm) surgically repaired with PRP. Patient demographics, biologic intervention, and adherence to the MIBO guidelines were systematically reviewed. Results A total of 19 studies (1005 patients) were included in this review. Across all studies, 58.5% of the MIBO checklist items for PRP were reported. Out of 47 checklist items, 19 were reported in over 85% of studies, whereas 22 were reported in less than half of studies. Details of whole-blood processing and characteristics, as well as PRP processing and characteristics, were reported inconsistently, and no study provided adequate information to enable the precise replication of preparation protocols for PRP. Conclusion This systematic review highlights the current reporting deficiencies within the scientific literature of important variables for evaluating PRP for full-thickness rotator cuff repair. There was widespread variability among published studies that evaluate PRP for this application and, more specifically, studies were limited by inconsistent universal reporting of whole-blood and PRP processing and postprocessing characteristics. To improve our understanding of biologic efficacy and to promote repeatability, stricter adherence to the MIBO guidelines is necessary. We propose that the checklist limitations be addressed and that modification of the MIBO guidelines be considered to improve the reporting of individual components within certain categories.

Abstract
BACKGROUND Type 2 failure is a big issue after suture-bridge rotator cuff repair, which may be because of stress concentration at the medial row stitches. We have been performing medial knot-tying after suture-bridge lateral row repair to avoid the stress concentration. This study aimed to evaluate clinical and radiological outcomes after arthroscopic rotator cuff repair using this technique. HYPOTHESIS This technique would yield better radiological outcomes with a reduced type 2 failure rate compared with reported outcomes after conventional suture-bridge repair. STUDY DESIGN Case series; Level of evidence, 4. METHODS The inclusion criteria of this study were (1) full-thickness tears, (2) primary surgery, and (3) minimum 2-year follow-up with pre- and postoperative magnetic resonance imaging (MRI). We investigated active ranges of motion (forward elevation and external rotation), as well as the Japanese Orthopaedic Association (JOA) and University of California, Los Angeles (UCLA), scores preoperatively and at the final follow-up. RESULTS This study included 384 shoulders in 373 patients (205 men and 168 women) with a mean age of 65 years (range, 24-89 years) at the time of surgery. The mean follow-up was 29 months (range, 24-60 months). There were 91 small, 137 medium, 121 large, and 35 massive tears. Postoperative MRI scans demonstrated successful repair in 324 shoulders (84.4%, group S) and retear in 60 shoulders (15.6%). Among 60 retears, 40 shoulders (67%) had type 1 failure (group F1) and 20 shoulders (33%) had type 2 failure (group F2). Forward elevation and external rotation significantly improved after surgery (P < .001 for both). Postoperative JOA and UCLA scores in group F2 were significantly lower than those in the other groups. CONCLUSION The medial knot-tying after suture-bridge lateral row repair demonstrated excellent functional and radiological outcomes after surgery, with a retear rate of 15.6%. The type 2 failure showed significantly inferior functional outcomes; however, the rate of type 2 failure was less relative to previous studies using conventional suture-bridge techniques. Our technique could be a good alternative to conventional suture-bridging rotator cuff repair because it may reduce the rate of postoperative type 2 failure.

Abstract
BACKGROUND High-tensile strength sutures are known to cut through tendon tissue when used for rotator cuff and other tendon repairs, resulting in mechanical failure. The purpose of this study was to test a new suture and compare it with an established suture in a controlled laboratory setting. METHODS Two sutures, Dynacord and FiberWire, both USP size No. 2, were passed through fresh infraspinatus tendons from 7 matched pairs of ovine shoulders (14 shoulders). Samples underwent cyclic testing for 1000 cycles, and the amount of cheese-wire tissue damage (tendon cut-through) was recorded. A clinical failure was defined as greater than 5 mm of tissue cut-through. RESULTS The mean amount of tendon cut-through was 3.72 ± 1.14 mm in the FiberWire specimens and 2.69 ± 1.02 mm in the Dynacord group. The difference was statistically significant (P = .012). In the matched-pair analysis, more tendon cut-through was noted with FiberWire in 13 specimens whereas a greater amount was found in only 1 Dynacord specimen. The FiberWire specimens showed 2 instances of tissue tendon cut-through exceeding 5 mm, defined as a clinical failure. CONCLUSIONS In this cadaveric ovine rotator cuff tendon model, we found less tendon cut-through from Dynacord suture compared with FiberWire. In addition, 2 of the FiberWire specimens showed complete tendon cut-through. Future studies focusing on patient-reported outcomes and healing rates with different types of suture materials are needed.

Does Medial-Row Fixation Technique Affect the Retear Rate and Functional Outcomes After Double-Row Transosseous-Equivalent Rotator Cuff Repair? Orthop J Sports Med 2019; 7:2325967119842881. [PMID: 31205960 PMCID: PMC6537075 DOI: 10.1177/2325967119842881] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/06/2023] Open
Abstract
Background: Double-row transosseous-equivalent (TOE) rotator cuff repair techniques have
been widely accepted because of their superior biomechanical properties when
compared with arthroscopic single-row repair. Concerns regarding repair
overtensioning with medial-row knot tying have led to increased interest in
knotless repair techniques; however, there is a paucity of clinical data to
guide the choice of technique. Hypothesis: Arthroscopic TOE repair techniques using knotless medial-row fixation will
demonstrate lower retear rates and greater improvements in the Constant
score relative to conventional knot-tying TOE techniques. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of 3 databases (PubMed, Cochrane, and Embase) was
performed using PRISMA (Preferred Reporting Items for Systematic
Meta-Analyses) guidelines. Inclusion criteria were English-language studies
that examined repair integrity or Constant scores after arthroscopic rotator
cuff repair with TOE techniques. Two investigators independently screened
results for relevant articles. Data regarding the study design, surgical
technique, retear rate, and Constant shoulder score were extracted from
eligible studies. A quality assessment of all articles was performed using
the Methodological Index for Non-Randomized Studies (MINORS) criteria. Results: The systematic review identified a total of 32 studies (level of evidence,
1-4) that met inclusion and exclusion criteria. Of the 32 studies, 5
reported on knotless TOE techniques, 25 reported on knot-tying TOE
techniques, and 2 reported on both. In the knotless group, retear rates
ranged from 6% to 36%, and Constant scores ranged from 38-65 (preoperative)
to 73-83 (postoperative). In the knot-tying group, retear rates ranged from
0% to 48%, and Constant scores ranged from 42-64 (preoperative) to 55-96
(postoperative). Conclusion: Despite several theoretical advantages of knotless TOE repair, both knotless
and knot-tying techniques reported considerable improvement in functional
outcomes after rotator cuff repair. Although tendon failure rates showed a
downward trend in knotless studies, additional prospective studies are
warranted to better understand the role of medial-row fixation on tendon
repair integrity and postoperative clinical outcomes.

Abstract
PURPOSE Platelet-rich plasma (PRP) is currently the most exploited strategy in the clinical practice to provide a regenerative stimulus for tendon healing. The aim of the present study was to systematically review the available evidence on the treatment of the main tendon disorders where PRP is currently applied. METHODS A systematic review of the literature was performed on the use of PRP as a treatment for tendinopathies focusing on the following sites: Achilles tendon, patellar tendon, rotator cuff tendons, and lateral elbow tendons. The following inclusion criteria for relevant articles were used: clinical trials written in English language up to 21 June 2016 on the use of PRP in the conservative or surgical treatment of the aforementioned tendinopathies. RESULTS The research identified the following clinical trials dealing with the application of PRP in the selected tendons: 19 papers on patellar tendon (6 being RCTs: 4 dealing with PRP conservative application and 2 surgical), 24 papers on Achilles tendon (4 RCTs: 3 conservative and 1 surgical), 29 on lateral elbow tendons (17 RCTs, all conservative), and 32 on rotator cuff (22 RCTs: 18 surgical and 3 conservative). CONCLUSION Patellar tendons seem to benefit from PRP injections, whereas in the Achilles tendon, PRP application is not indicated neither as a conservative approach nor as a surgical augmentation. Lateral elbow tendinopathy showed an improvement in most of the high-level studies, but the lack of proven superiority with respect to the more simple whole-blood injections still questions its use in the clinical practice. With regard to rotator cuff pathology, the vast majority of surgical RCTs documented a lack of beneficial effects, whereas there is still inconclusive evidence concerning its conservative application in rotator cuff disorders. LEVEL OF EVIDENCE Systematic review of level I-IV trials, Level IV.

Abstract
BACKGROUND Platelet-rich plasma (PRP) has been applied as an adjunct to rotator cuff repair to improve tendon-bone healing and potentially reduce the incidence of subsequent tendon retears. PURPOSE To investigate whether the midterm clinical and radiographic outcomes of arthroscopic supraspinatus repair are enhanced after repeated postoperative applications of PRP. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS A total of 60 patients (30 control; 30 PRP) were initially randomized to receive 2 ultrasound-guided injections of PRP to the tendon repair site at 7 and 14 days after double-row arthroscopic supraspinatus repair or not. A total of 55 patients (91.7%) underwent a clinical review and magnetic resonance imaging (MRI) at a mean of 3.5 years after surgery (range, 36-51 months). Patient-reported outcome measures (PROMs) included the Constant score, Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire, Oxford Shoulder Score (OSS), and visual analog scale (VAS) for pain. Global rating of change (GRC) scale and patient satisfaction scores were evaluated. Structural integrity of the surgical repair was assessed via MRI using the Sugaya classification system. RESULTS At the midterm review, there was no difference between the groups for any of the PROMs. No differences between the groups were demonstrated for the subjective and range of motion subscales of the Constant score, although a significantly higher Constant strength subscale score was observed in the PRP group (3.3 points; 95% CI, 1.0-5.7; P = .006). There was no evidence for any group differences in MRI scores or retear rates, with 66.7% of PRP patients and 64.3% of control patients rated as Sugaya grade 1. Two control patients had symptomatic retears (both full thickness) within the first 16 weeks after surgery compared with 2 PRP patients, who suffered symptomatic retears (both partial thickness) between 16 weeks and a mean 3.5-year follow-up. CONCLUSION Significant postoperative clinical improvements and high levels of patient satisfaction were observed in patients at the midterm review after supraspinatus repair. While pain-free, maximal abduction strength was greater in the midterm after PRP treatment, repeated applications of PRP delivered at 7 and 14 days after surgery provided no additional benefit to tendon integrity.

Abstract
Although uncommon, rotator cuff tears that occur medially at the musculotendinous junction can result from acute trauma, anatomic force imbalance, or medial row cuff failure following a previous rotator cuff repair. The quality of the torn muscle and tendon along with the length of the remnant tendon stump should be considered before deciding on the most appropriate repair technique. When muscle and tendon quality are sufficient, the tear can often be repaired directly to the remnant tendon stump and compressed onto the greater tuberosity. If the remnant tendon stump is degenerative, of insufficient length, or lacks tendon in which to place sutures, an allograft patch can be used to augment the repair. When the quality of the remaining muscle and tendon are poor or when the muscle is retracted too far medially and is nonmobile, a bridging technique such as superior capsule reconstruction is preferable. The purpose of this report is to (1) highlight that medial cuff failure can occur both primarily and after previous repair; (2) define and classify the 3 major tear patterns that are encountered, and (3) describe the authors' preferred techniques for medial cuff repair that specifically address each of the major tear patterns.

Abstract
Despite advances in surgical reconstruction of chronic rotator cuff (RC) tears leading to improved clinical outcomes, failure rates of 13-94% have been reported. Reasons for this rather high failure rate include compromised healing at the bone-tendon interface, as well as the musculo-tendinous changes that occur after RC tears, namely retraction and muscle atrophy, as well as fatty infiltration. Significant research efforts have focused on gaining a better understanding of these pathological changes in order to design effective therapeutic solutions. Biological augmentation, including the application of different growth factors, platelet concentrates, cells, scaffolds and various drugs, or a combination of the above have been studied. It is important to note that instead of a physiological enthesis, an abundance of scar tissue is formed. Even though cytokines have demonstrated the potential to improve rotator cuff healing in animal models, there is little information about the correct concentration and timing of the more than 1500 cytokines that interact during the healing process. There is only minimal evidence that platelet concentrates may lead to improvement in radiographic, but not clinical outcome. Using stem cells to biologically augment the reconstruction of the tears might have a great potential since these cells can differentiate into various cell types that are integral for healing. However, further studies are necessary to understand how to enhance the potential of these stem cells in a safe and efficient way. This article intends to give an overview of the biological augmentation options found in the literature.

Abstract
PURPOSE To evaluate the chondrogenic potential of platelet concentrates on human subchondral mesenchymal progenitor cells (MPCs) as assessed by histomorphometric analysis of proteoglycans and type II collagen. Furthermore, the migratory and proliferative effect of platelet concentrates were assessed. METHODS Platelet-rich plasma (PRP) was prepared using preparation kits (Autologous Conditioned Plasma [ACP] Kit [Arthrex, Naples, FL]; Regen ACR-C Kit [Regen Lab, Le Mont-Sur-Lausanne, Switzerland]; and Dr.PRP Kit [Rmedica, Seoul, Republic of Korea]) by apheresis (PRP-A) and by centrifugation (PRP-C). In contrast to clinical application, freeze-and-thaw cycles were subsequently performed to activate platelets and to prevent medium coagulation by residual fibrinogen in vitro. MPCs were harvested from the cortico-spongious bone of femoral heads. Chondrogenic differentiation of MPCs was induced in high-density pellet cultures and evaluated by histochemical staining of typical cartilage matrix components. Migration of MPCs was assessed using a chemotaxis assay, and proliferation activity was measured by DNA content. RESULTS MPCs cultured in the presence of 5% ACP, Regen, or Dr.PRP formed fibrous tissue, whereas MPCs stimulated with 5% PRP-A or PRP-C developed compact and dense cartilaginous tissue rich in type II collagen and proteoglycans. All platelet concentrates significantly (ACP, P = .00041; Regen, P = .00029; Dr.PRP, P = .00051; PRP-A, P < .0001; and PRP-C, P < .0001) stimulated migration of MPCs. All platelet concentrates but one (Dr.PRP, P = .63) showed a proliferative effect on MPCs, as shown by significant increases (ACP, P = .027; Regen, P = .0029; PRP-A, P = .00021; and PRP-C, P = .00069) in DNA content. CONCLUSIONS Platelet concentrates obtained by different preparation methods exhibit different potentials to stimulate chondrogenic differentiation, migration, and proliferation of MPCs. Platelet concentrates obtained by commercially available preparation kits failed to induce chondrogenic differentiation of MPCs, whereas highly standardized PRP preparations did induce such differentiation. These findings suggest differing outcomes with PRP treatment in stem cell-based cartilage repair. CLINICAL RELEVANCE Our findings may help to explain the variability of results in studies examining the use of PRP clinically.

Ultrasonic evaluation of the repair integrity can predict functional outcomes after arthroscopic double-row rotator cuff repair. Knee Surg Sports Traumatol Arthrosc 2015; 23:376-85. [PMID: 25600261 DOI: 10.1007/s00167-015-3505-z] [Citation(s) in RCA: 49] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2014] [Accepted: 01/09/2015] [Indexed: 12/21/2022]
Abstract
PURPOSE Despite proven accuracy of US for the evaluation of rotator cuff integrity, there is no US-based classification for this purpose. This study aimed to assess US for the evaluation of rotator cuff repair integrity in accordance with a well-established MRI classification. METHODS The authors retrospectively reviewed 257 patients who underwent arthroscopic double-row suture anchor repair for rotator cuff tears. Post-operative function was rated using the Constant score, the UCLA rating and the SSV, whereas repair integrity was assessed using US as described in the MRI classification of Sugaya et al. RESULTS A total of 212 patients aged 55.6 ± 9.8 years had complete functional and radiographic assessments at a mean follow-up of 36.8 ± 11.6 months. Using all three ratings, repairs of Type I had highest scores, repairs of Type II had discernibly lower scores, whereas repairs of Types III, IV and V had similar intermediate scores. CONCLUSION Comparison of the UCLA scores with those of Sugaya et al. revealed similar scores for repairs of Type I and of Type V. The scores are less comparable for repairs of Types II, III and IV, because US does not allow identification of partial tears if shielded by bony structures and because partial tears correspond to minimal impairment. The study reveals that US is an adequate imaging modality to classify rotator cuff repair integrity, which could reduce economic and practical burdens of CTA, MRI or MRA. The results also confirm that post-operative repair integrity and functional outcome depend on pre-operative tear size and fatty infiltration, which provides clinicians with reasoning for early surgical repair and warning of the risks of strenuous activity for patients with larger tears. LEVEL OF EVIDENCE Prognostic study, Level IV.
